Double-shaft rocking sieve

Abstract

The invention relates to a double-shaft rocking sieve which relates to a papermaking and artificial board industry and is used for sieving materials in a material preparing work section. The double-shaft rocking sieve comprises a plurality of layers of parallel sieve plates and the sieve plates are flexibly suspended on a fixing framework; each one of two sides of each sieve plate is respectively provided with a rotary shaft for connecting each sieve plate in a penetrated mode; and each rotary shaft is provided with an overweight block. According to the double-shaft rocking sieve, the rotary shafts at the two sides of the sieve plate and the overweight blocks are arranged so that the whole sieve plate can rock stably and the sieving effect is good; and meanwhile, the middle part of the whole sieve plate is not blocked by a rotary shaft part so that the sieving area is large, the efficiency is high and the material mobility is good.

Description

technical field [0001] The invention relates to a double-shaft oscillating screen used for screening materials in a material preparation section in the papermaking and wood-based panel industries. Background technique [0002] The swinging screen is a device used for screening raw materials such as wood chips and bamboo chips in the papermaking and wood-based panel industries. It usually includes a multi-layer screen body flexibly suspended on the frame, and a rotating shaft driven by a motor is connected to the middle of the multi-layer screen body. , one end of the rotating shaft is equipped with an eccentric block. During the working process, the rotating eccentric weight makes the whole screen body, rotating shaft and motor produce a swing action to realize the screening of materials. In this structure, since the rotating shaft and weight block are only installed in the middle of the screen body, not only the rotating shaft will occupy the area of ​​the sieve plate, whi...

AI Technical Summary

Problems solved by technology

In this structure, since the rotating shaft and the weight block are only installed in the middle of the screen body, not only the rotating shaft will occupy the area of ​​the sieve plate, which will affect the screening efficiency and the fluidity of the material, but also the poor balance during the swing process will affect the operation reliability.
